I am using this code to connect using /v3/connect

CodeExchangeRequest codeRequest = new CodeExchangeRequest(
            "http://localhost:8085/api/v1/mailing/oauth/exchange", 
            code, // authorization code
            "c9314065-1236-412b-a943-9b947170d56b", // client ID
            null, 
            "nylas"
        );
    
        try {
            CodeExchangeResponse codeResponse = nylasClient.auth().exchangeCodeForToken(codeRequest);

And i am getting this Error: Received an error but could not parse response from the server: Method Not Allowed

NB : My code was working fine
